Ft. Lauderdale, FL, United States, 2006/09/26 - Firstly, thanks so much to those of you participated in the hybrid diesel-electric reader's poll we held recently - your comments are extremely valuable to us!
We wish to address a few of the questions and possible misconceptions elicited in your replies. Most seem to be motor related, which is not surprising concerning the revolutionary aspects of the Hybrid system.
Bearing wear, this is a spurious concern, the designed life cycle of 20,000 hrs. is equal to Five (yes 5) circumnavigations, or 10 Ė 20 years in private service, further these are relatively cheap "off the shelf" bearings easily replaced by any mechanic's shop.
Itís important to note that the controller actually controls shaft rotation according to the Mode of operation (5 modes) and the state of the batteries charge.
Our experience leads us to predict a 1,000 mile range under power if the additional fuel tank option is chosen.
The generators consume between .9 gph up to 1.9 gph for the 21KW genset at maximum power, note max is rarely used and only for short periods.
Noise levels of the shafts are maximum 46db, while the genset is quieter than a standard diesel.
Duty cycle Ė note that in normal day sailing use the genset will probably not start, as you may motor up to one hour from the slip, sail all day (charging as necessary by regeneration) then furl sails and motor back into the slip...all without requiring generator use. Thus most of the time aboard is completely silent or if motoring, the sound is similar to two battery drills.
Transporting or Cruising Long Distance
Long distance motoring will require continuous generator use. The generators power is available for ships services (Microwave, Air Conditioning etc.) depending on the position of the mode switch.
Finally two points relate to the design of the vessel itself, its important to note that this like all Lagoons is built to very stringent CE standards. As they all sail to the States on their own bottoms, they are thoroughly shaken down before handover.
Vertical Salon Windows
One of our reader's mentioned that he was surprised by the fact that Lagoon continues to implement their trademark vertical salon windows into their designs, as this contributes to "the drag factor".
Aerodynamically speaking, the low winds speeds in question have only a small affect on boat speed especially when compared with Hull friction. This is a trade off for vastly increased visibility and usable floor space inside. Once you sail it this will be last thing on your mind, except to notice how cool and shady it is aboard. Note as well that the Pedigree of her Naval architects in unmatched for both racing and cruising Multihulls, with more than twenty years experience and thousands of successful designs sailing.
